Committed Use Discounts: Discounts for committing to use a certain amount of resources for 1 or 3 years.
Committed Use Discounts (CUDs) reward users for committing to a specific resource usage level for a 1- or 3-year term, providing significant cost savings.
- B
Preemptible VMs: Short-lived, lower-cost instances that can be terminated at any time.
Preemptible VMs are spot instances that are cheaper but can be preempted (terminated) by Google Cloud when resources are needed elsewhere.
- C
Sustained Use Discounts: Automatic discounts for running instances for a significant portion of a month.
Sustained Use Discounts (SUDs) are automatically applied when an instance runs for more than 25% of a month, offering incremental savings.
- D
Custom Machine Types: Creating VMs with specific vCPU and memory configurations to match workload needs.
Custom machine types allow tailoring vCPU and RAM to avoid overprovisioning and reduce costs.
- E
Committed Use Discounts: Short-lived, lower-cost instances that can be terminated at any time.
Why wrong: Incorrect — this describes Preemptible VMs, not Committed Use Discounts.
- F
Preemptible VMs: Discounts for committing to use a certain amount of resources for 1 or 3 years.
Why wrong: Incorrect — this describes Committed Use Discounts, not Preemptible VMs.

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Committed Use Discounts: Discounts for committing to use a certain amount of resources for 1 or 3 years.
Common cost management techniques on Google Cloud include Committed Use Discounts (long-term commitment savings), Preemptible VMs (short-lived cheaper instances), Sustained Use Discounts (automatic monthly usage discounts), and Custom Machine Types (tailored VMs). The distractors swap definitions between related practices.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
